Abstract: Use of aqueous dispersions of (co)polymers (I) of at least one ethylenic unsaturated monomer for preparing textile additives, where (I) is prepared in the presence of at least two water-soluble polymer in which at least one water-soluble polymer is: graft polymer of vinyl acetate and/or vinyl propionate on polyalkylene glycol or polyalkylene glycol substituted (at one/two side) with alkyl, carboxyl or amino groups. Use of aqueous dispersions of (co)polymers (I) of at least one ethylenic unsaturated monomer for preparing textile additives (printing paste for the pigment printing with a dynamic viscosity of 0.1-59 dPas, measured at 20[deg]C, printing paste for the transfer printing, the dispersion printing, the printing with acid and metal complex coloring materials, the reactive printing or the vat printing, dye liquors for the textile coloring, coating agent, equipment fleets), where (I) is prepared in the presence of at least two water-soluble polymer in which at least one water-soluble polymer is: graft polymer (a1) of vinyl acetate and/or vinyl propionate on polyalkylene glycol or polyalkylene glycol substituted (at one/two side) with alkyl, carboxyl or amino groups, copolymers (a2) from alkylpolyalkylene glycol(meth)acrylate and (meth)acrylic acid, polyalkylene glycol (a3) or polyalkylene glycol (a4) substituted (at one/two side) with alkyl, carboxyl or amino groups and the other water-soluble polymer is hydrolyzed copolymer (b1) from vinylalkylether and maleic acid anhydride as free poly acid or partially neutralized with alkali metal hydroxides or ammonium bases, starch (b2) (optionally modified), synthetic copolymers (b3) (obtained by copolymerization of one or more non ionic monoethylenic unsaturated monomers, one or more cationic monoethylenic unsaturated monomers and optionally one or more anionic monoethylenic unsaturated monomers, where the molecular portion of polymerized cationic monoethylenic unsaturated monomers is higher than the portion of the polymerized anionic monoethylenic unsaturated monomers). Independent claims are also included for: (1) a method for preparing: printing paste for the pigment printing with a dynamic viscosity of 0.1-59 dPas, measured at 20[deg]C, printing paste for the transfer printing, dispersion printing, printing with acid- and metal complex coloring materials, the reactive printing or vat printing; dye liquors for the textile coloring; coating agent for textiles; or equipment fleets for textiles using (I); (2) printing paste for the pigment printing with a dynamic viscosity of 0.1-59 dPas, measured at 20[deg]C, printing paste for the transfer printing, dispersion printing, printing with acid- and metal complex coloring materials, the reactive printing or vat printing; dye liquors for the textile coloring; coating agent; and equipment fleets prepared by the method; (3) a method for printing on textiles using the printing paste; (4) a method for coloring textile using the dye liquor; (5) a method for coating textile using the coating agent; (6) a method for equipping textile using the equipment fleets; (7) textile substrates, printed by the method and (8) a pigment preparation comprising (I).
